Abstract

The invention discloses a rotor lamination of a permanent magnet motor. The rotor lamination comprises a rotor lamination body. Actuating lever grooves are formed on the outer circumference of the rotor lamination body. Primary magnetic steel grooves are formed below the actuating lever grooves. The two sides of the primary magnetic steel groove are provided with a secondary magnetic steel groove respectively. Upper magnetic isolation bridges A are arranged between the actuating lever grooves and the primary magnetic steel grooves. Magnetic isolation bridges B are arranged between the primary and secondary magnetic steel grooves. The upper magnetic isolation bridge A is 1.10 to 1.13mm wide, and the magnetic isolation bridge B is 1.4 to 1.44mm wide. The rotor lamination of the permanent magnet motor has a rational design and a compact structure; a rare earth permanent magnet synchronous motor produced by the rotor lamination simultaneously has rational locked rotor torque, rational minimum torque, a rational back electromotive force and remarkably power saving effects, and can meet the requirements of normal starting and a small number of broken ends of a spinning frame.

Description

A kind of permanent magnet motor rotor punching
Technical field
The present invention relates to a kind of permanent magnet motor rotor punching.
Background technology
In the prior art; The permanent magnet machine rotor punching is because the running of can not pulling in smoothly behind the reasonable inadequately electric motor starting of rotor punching structural design; Because the rotor punching structural design is reasonable inadequately, brings the unreasonable locked-rotor torque that causes of magnetic intensity bigger than normal, is applied in when starting on the weaving spinning frame and breaks end too much; Simultaneously, unreasonable the causing of back electromotive force do not economized on electricity.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can satisfy that spinning frame normally starts, little breakage, the permanent magnet motor rotor punching of tangible power savings is arranged again.
The present invention for realizing the technical scheme that above-mentioned purpose adopted is: a kind of permanent magnet motor rotor punching; Comprise the rotor punching body; The external circumference of said rotor punching is provided with the starting bar groove, and said starting bar groove below is provided with main magnet steel groove, and the both sides of said main magnet steel groove are provided with secondary magnet steel groove; Be provided with between said starting bar groove and the main magnet steel groove at a distance from magnetic bridge A; Be provided with between said main magnet steel groove and the secondary magnet steel groove at a distance from magnetic bridge B, the said width of going up at a distance from magnetic bridge A is 1.10-1.13mm, and said is 1.4-1.44mm at a distance from magnetic bridge B.
Said rotor punching body diameter phi is 167-167.03mm.
Said starting bar slot length C is 10.1-10.3mm, and starting bar groove width D is 3.2-3.4mm.
Said starting bar groove is provided with 25-28.
Said main magnet steel slot length E is 25.1-25.4mm, and main magnet steel well width F is 8.1-8.4mm.
A kind of permanent magnet motor rotor punching of the present invention; Reasonable in design, compact conformation; Adopt this rotor punching to produce rare-earth permanent-magnet synchronous motor and have rational locked-rotor torque, rational pull up torque is arranged again, also have rational back electromotive force simultaneously; Can satisfy that spinning frame normally starts, little breakage, tangible power savings is arranged again.
